I have him in a 2 gallon bin. The water stays at the right Temp. He is just laying on the bottom. It looks like he can't swim well at all. I don't know if it is just because he has been in a cup for a while? I just want this little guy to be all right. He LOOKS healthy. Ha hasn't been eating either. But none of mine have eaten well for the first couple days. Sooo, I don't know... Anything I should do to make him feel better?
